Well, I don't have any case at hand where immediate value would be of
*that* great value. FWIW, when I run into "too long string value"
issue I though about was to have shorter summary for vector, e.g. "[2]",
but then figured it's additional work, and folks did not complain
about "{...}" so far.

FWIW, I was driving exactly at this simplicity point :-)

Great, thanks!
